The most common paint problems in Michigan homes are peeling and blistering, and both usually come from moisture getting behind the paint rather than from bad paint.
Freeze-thaw winters, humid summers and older homes with many layers of paint make water the main enemy: it gets in through failed caulk, overflowing gutters, siding too close to the soil, or warm indoor air pushing out through the walls.
Here’s how to name what you’re seeing and fix it, from our exterior painting work across Macomb and Oakland counties.
| What you see | Usually means | Check first |
|---|---|---|
| Paint lifting in strips or flakes | Peeling | Gutters, caulk, soil contact |
| Bubbles in the paint | Blistering | What’s under a cut bubble |
| Scaly, cracked pattern | Alligatoring | Age and number of layers |
| White powder on your hand | Chalking | Rub test on sunny walls |
| Black or gray spots | Mildew or dirt | Bleach drop test |
Sticky brown streaks on fresh paint are usually surfactant leaching (problem 6). A small, dry indoor peel is a DIY fix; anything outside or recurring needs a pro.
Of the 102 paint-problem calls we handled in September, 44% were peeling and 32% were blistering.
Why Michigan Homes Get So Many Exterior Paint Problems
Water behind the paint freezes, expands and thaws all winter, loosening the film. Warm indoor air also pushes moisture out through older walls; an insulation or ventilation contractor can judge that part.
Many Macomb and Oakland homes are postwar ranches, colonials and bungalows with decades of paint, often old oil under latex. Shaded north walls and lakeshore humidity in Harrison Township and St. Clair Shores feed mildew. For how long a sound finish should last, see our post on exterior paint lifespan.
1. Peeling and Flaking Paint: The Problem We See Most
Peeling paint lifts away in strips or flakes, often to bare wood; cracking starts as lines in paint still attached. The cause is usually a moisture path (gutters, failed caulk, siding near the soil, roof or flashing leaks, humid indoor air), then poor prep, then incompatible paint such as latex over glossy oil.
The fix runs in order: stop the water, scrape back to a firmly bonded edge, spot-prime bare wood, repaint. Soft wood, gutters or roof leaks go to a carpenter, gutter installer or roofer first. If your siding is peeling, request an inspection and we’ll trace the source first.
Indoors, peeling usually traces back to humidity or paint over a dirty or glossy surface; our guide to peeling wall paint covers it.
2. Blistering and Bubbling Paint
Paint blistering comes in two kinds. Cut into a moisture blister and you’ll find water or bare wood; a heat blister shows dry paint below, from dark colors on hot south and west walls, painting in direct sun or recoating too soon. In a post-1978 home, or after a lead test, slice one open to check.
Moisture blisters need the source fixed and the area taken back to sound paint. Heat blisters need scraping, sanding and repainting in the right conditions.
3. Cracking and Alligatoring
Alligatoring is a scaly, reptile-skin pattern of cracks, common where hard old oil sits under flexible latex or decades of layers have built up. The old layers themselves are failing, so the fix is usually stripping, not another coat.
4. Chalking and Fading
Chalking paint leaves white powder on a hand or dark cloth, worst on sun-facing walls. A little chalk just means the paint is aging, as fading does, but heavy chalk has to be scrubbed away so the next coat can bond.
5. Mildew (and How to Tell It From Dirt)
Dab diluted bleach on a spot: if it fades within a minute or two, it’s mildew; if it stays dark, it’s dirt. Mildew thrives on shaded walls and near water, and spreads through fresh paint unless killed and cleaned first. Wear gloves and eye protection, and never mix bleach with ammonia-based cleaners. Large indoor mold growth is a remediation job, not a paint job.
6. Brown or Sticky Streaks on New Paint (Surfactant Leaching)
Sherwin-Williams describes surfactant leaching as water-soluble ingredients in latex paint rising to the surface as tan, brown or clear sticky spots. Cool weather slows curing, and dew or rain on uncured paint draws them out. A plain-water rinse usually removes it; repaint only if stains set. That’s why fall work here needs careful timing.
Paint Problems on Painted Brick
Peeling on painted brick usually means trapped moisture, and white crystal deposits (efflorescence) show water moving through the masonry. Mortar or structural issues need masonry work before paint.
Common Interior Paint Problems We See
- Bathroom ceilings peel from steam
- Kitchen walls and cabinets chip when grease or the wrong product stops paint bonding
- Roller marks, flashing and patches showing through usually mean prep or primer was skipped.
- Textured ceilings from before the 1980s should be tested for asbestos before scraping.
Can You Just Paint Over It?
Painting over peeling paint works only in narrow cases, and the same goes for most of these problems:
| Problem | Paint over it? | What comes first |
|---|---|---|
| Small, dry, isolated peel | Yes, after prep | Scrape, feather-sand, spot-prime |
| Peeling that keeps returning | No | Fix the water source |
| Moisture blisters | No | Fix moisture, remove blisters |
| Alligatoring | No | Strip to a sound surface |
| Chalking | Yes, after washing | Wash until a rub comes clean |
Mildew needs killing and cleaning first; surfactant leaching usually needs only a rinse.
How to Prevent Paint Problems on a Michigan Home
- Keep water off the paint: clear gutters, extend downspouts, keep caulk sound and keep siding clear of soil and mulch.
- Paint in the right conditions; see our seasonal painting guide.
- Treat prep as most of the job: wash, scrape, sand, prime bare wood.
- Match the product to the surface.
- Walk the house each spring after the thaw, with our exterior maintenance tips.
Questions Michigan Homeowners Ask About Paint
What is the most common paint problem on Michigan homes?
Peeling, followed by blistering, and moisture is usually behind both.
Why is my outside paint peeling after one winter?
Water likely got behind it through gutters, caulk or soil contact, then froze, or the paint never bonded to a dirty or glossy surface.
What causes paint to bubble?
Moisture under the film, or heat from painting in direct sun or recoating too soon.
Can you paint over peeling paint?
Only after the cause is fixed, loose paint is scraped to a firm edge and bare spots are primed.
How do I know if my old paint contains lead?
Assume it might in a pre-1978 home, and test before any scraping or sanding.
Is it too late in the year to paint my house’s exterior in Michigan?
It depends on overnight temperatures and dew, not the date.
